The equipment needed while using the oven includes the following: lab coat, eye/face protection, heat resistant gloves. Rubber sleeve protectors and aprons will also be helpful in using the ovens. If the proper safety guidelines and equipment are used, the lower the chance of problems are to occur. [4]
A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring.
Bunsen sought to improve existing laboratory burner lamps as regards economy, simplicity, and flame temperature, and adapt them to coal-gas fuel. While the building was under construction in late 1854, Bunsen suggested certain design principles to the university's mechanic, Peter Desaga , and asked him to construct a prototype.
The Teclu burner is an ambient air laboratory gas burner, that was created by Romanian chemist Nicolae Teclu in 1882. The burner is most commonly used to heat substances in a laboratory, can be used for sterilisation and sometimes it is used for soldering or glasswork. [1] It is commonly made from brass or iron.
The Méker burner heating power can be around 3.6 kW using liquefied petroleum gas. [2] Flame temperatures of up to 1,100–1,200 °C (2,000–2,200 °F) are achievable. Compared with a Bunsen burner, the lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and ...
They were originally developed by Louis Pasteur, [1] and are essentially the same as fan ovens used for cooking food. Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy , the inner layer being a poor conductor and outer layer being metallic.

Crucibles used in Czochralski method Melting gold in a graphite crucible Three crucibles used by Thomas Edison. Crucibles are used in the laboratory to contain chemical compounds when they are heated to extremely high temperatures. Crucibles are available in several sizes and typically come with a correspondingly-sized lid. [20]
